Model Answer

Inter-State rivers are shared resources whose management requires balancing State interests with basin-wide sustainability. The 2026 Bihar–Jharkhand agreement, resolving a nearly 25-year Sone water dispute through dialogue, illustrates the importance of cooperative federalism in water governance.

Why inter-State water disputes persist

1. Competing developmental needs create conflicts between riparian States. e.g: Irrigation, drinking water and industry.
2. Uneven spatial and seasonal water availability intensifies scarcity.
3. Historical agreements become contentious after administrative reorganisation. e.g: Bihar–Jharkhand bifurcation.
4. Upstream projects can affect downstream water availability.
5. Climate change increases rainfall variability and alters river flows.
6. Inadequate real-time hydrological data creates disagreements over water availability.
7. Political mobilisation often transforms technical disputes into federal conflicts.

Why negotiated mechanisms matter

1. Dialogue allows flexible solutions beyond adversarial adjudication.
2. Agreements can simultaneously accommodate different State requirements.
3. Federal mediation can help overcome prolonged political stalemates.
4. Zonal Councils and the Inter-State Council provide institutional spaces for consultation.
5. The Sone agreement demonstrates mutually negotiated allocation. e.g: Bihar receives 5.75 MAF and Jharkhand 2 MAF.
6. Cooperation enables better utilisation of shared infrastructure. e.g: Indrapuri Barrage and canal network.

Way Forward

1. Shift from State-wise allocation towards integrated river-basin management.
2. Establish transparent real-time hydrological data-sharing mechanisms.
3. Strengthen mediation through the Inter-State Council and Zonal Councils before disputes require adjudication.

Inter-State rivers should be governed as shared ecological and economic systems rather than territorial resources. The Sone agreement shows that sustained dialogue, credible data and cooperative institutions can transform water disputes into opportunities for federal cooperation.
